Imaging excised apical plasma membrane patches of MDCK cells in physiological conditions with atomic force microscopy
We combined the patch-clamp technique with atomic force microscopy (AFM) to visualize plasma membrane proteins protruding from the extracellular surface of cultured kidney cells (MDCK cells). To achieve molec...

Molecular weights of individual proteins correlate with molecular volumes measured by atomic force microscopy
Proteins are usually identified by their molecular weights, and atomic force microscopy (AFM) produces images of single molecules in three dimensions. We have used AFM to measure the molecular volumes of a nu...

ATP-Induced Shape Change of Nuclear Pores Visualized with the Atomic Force Microscope
Bidirectional transport of molecules between nucleus and cytoplasm through the nuclear pore complexes (NPCs) spanning the nuclear envelope plays a fundamental role in cell function and metabolism. Nuclear imp...

Volume dynamics in migrating epithelial cells measured with atomic force microscopy
Migration of transformed renal epithelial cells (transformed Madin-Darby canine kidney cells, MDCK-F cells) relies on the activity of a Ca2+-sensitive K+ channel (IK channel) that is more active at the rear end o...

Secretion Pores in Human Endothelial Cells during Acute Hypoxia
Weibel-Palade bodies (WPB) are endothelial vesicles that store von Willebrand factor (vWF), involved in the early phase of hemostasis. In the present study we investigated the morphodynamics of single WPB plas...

Endothelial Cell Swelling by Aldosterone
There is accumulating evidence that mineralocorticoids not only act on kidney but also on the cardiovascular system. We investigated the response of human umbilical venous endothelial cells (HUVECs) to aldoste...

Open AccessMss4 protein is a regulator of stress response and apoptosis
Mss4 (mammalian suppressor of Sec4) is an evolutionarily highly conserved protein and shows high sequence and structural similarity to nucleotide exchange factors. Although Mss4 tightly binds a series of exocy...

Nuclear heparanase-1 activity suppresses melanoma progression via its DNA-binding affinity
Heparanase-1 (HPSE) plays a pivotal role in structural remodeling of the ECM and the glycocalyx, thus conferring protumorigenic, proangiogenic and prometastatic properties to many cancer entities. In addition ...

Open AccessBladder cancer-derived interleukin-1 converts the vascular endothelium into a pro-inflammatory and pro-coagulatory surface
Bladder cancer cells orchestrate tumour progression by pro-inflammatory cytokines. Cytokines modulate the local tumour microenvironment and increase the susceptibility of tumour distant tissues for metastasis....
